Here we consider the famous block signal with \(K = 11\)  change-points. As in [1]} we choose 2048 observations, \(\mathcal {N}(0, 7^2)\)  errors as before, and set change-points at \(205, 267, 308, 472, 512, 820, 902, 1332, 1557, 1598, 1659\)  with corresponding function values 0, \(14.64\) , \(-3.66\) , \(7.32\) , \(-7.32\) , \(10.98\) , \(-4.39\) , \(3.29\) , \(19.03\) , \(7.68\) , \(15.37\) , 0; see Figure REF .
